Where was John Surratt on April 14, 1865 ?

[RJNorton]

Atzerodt said on July 6 (almost 3 months after the fact and the day before his execution) that he had seen Surratt on April 14 and that he (Surratt) was then staying at the Herndon House. Also he said that Booth told him that Surratt was with him (Booth) in Ford's Theatre

Kees, I recall where Atzerodt claimed Booth said (to Atzerodt) that he had seen Surratt in Washington on the 14th, and that Surratt was going to help in the box at Ford's. However, I do not recall Atzerodt himself saying he had seen Surratt on the 14th in Washington. Could you possibly post what you found regarding what Atzerodt said? Many thanks.
